Y., and Arthur P. Schulz, Rockford, Ill., assignors to Teller StoveDesigning Corporation, New York, N. Y., a corporation of New York 8Claims. (Cl. 126-340) This invention relates to cooking stove and rangeconstruction, and is a division of our original application Serial No.647,036, filed December 13, 1932. w

The particular features of the present invention reside in the specificoven structure, and in the arrangement of the cooking vessel rack,whereby said rack, pivoted upon a vertical axis within the ovencompartment, may be interconnected with the oven door in such'mannerthat, when the door is opened, therack is oscillated upon the pivots,and the supports for the cooking vessels carried thereby moved out ofthe oven into a position conveniently accessible to the person using therange.

A further feature resides in mechanism carried by the oven door andselectively connectible with the swinging rack, to the end that'the ovendoor may be opened or closed with or without simultaneous operation ofthe rack.

These and many other features of advantage will be apparent to thosefamiliar with the operation of such apparatus, and the various objectswill become quite evident upon reference to the accompanying drawingsand specification.

In the accompany drawings:

Fig. 5 is a detail sectional view through the rack support.

Fig. 6 is a horizontal section taken through the range on substantiallythe line 66 of Fig. 3, and

Figure '7 is a detail view similar to Fig. 4, but

showing the parts arranged so that the shifter plate renders the doorand rack parts relatively inoperative.

Referring now to the drawings by numerals of reference, I, designatesgenerally the range, having the usual sides 2, back wall 3, and thefront, which latter is closed by a series of doors and panels indicatedat 4, 5, 6 and 1 respectively.

The insulated cooking top 8 of enameled sheet metal or other suitablematerial, has therein, a plurality of openings 9, according'to anarrangement peculiar to this invention, the particular function of whichwill be apparent as the description advances, and as more particularlyset forth in our original application hereinbefore-referred to.

Specifically, the openings 9 are arrangedin the form of the letter L,the long leg of which lies toward and parallel with the rear edge of thecooking top 8, while the shorter leg lies adjacent to and parallel withthe right hand edge of the cooking top 8 thus providing a rectangularworking top space 10, surrounded on two sides by the series of openings9, .beneath which aresuitably supported the burners -I I, said openingshaving utensil supporting grids l2.

Referring at this time to Figures 2 and 6, it will be observed that therange is divided into a plurality of compartments l4 and Hi, the formerconstituting the combined oven and broiler compartment, while the latterconstitutes an L-' shaped space which underlies the openings in thecooking top, and in the upper portion of which L-shaped compartment, aresuitably supported the burners ll.

These compartments M and I5, are defined by a longitudinal insulatedpartition I6 and a transverse insulated partition ll, the latterterminating short of the back wall 3 of the range, each of thepartitions terminating at a point above the bottom l8 of an auxiliarycompartment l9 which is provided with trackways for a sliding drawer 2|,the front of which latter takes the form of the panel 6, above referredto.

As distinguished from ovens of the usual character, the present ovencompartment I4 is elongated in form, and relatively shallow as shown inFigure 6, the greater length being in the direction of the width of'therange as shown. By'

this arrangement and form of oven, we are able to obtain an oven of, acapacity substantially that of an oven such as employed in the usualrange, in which it extends throughout the depth of the range body.

At the same time, as distinguished from ranges of the ordinary type, thetop of the oven extends up to the cooking and working top, without theintervention of the regular burner compartment. This of course, ispermitted through the arrangement of the series of burners to the sideand back of the upper portion of said oven.

By the arrangement shown, not only are the burners so positioned thatthey permit elevation of the oven and broiler compartment H to anaccessible working position, but at the same time, an insulated workingspace H), convenient to ment which may serve for any purpose for whichit may be intended, and the panel I, on which are mounted the handlesfor the burner valves or for electric switches, when the range isutilized as an electric cooking apparatus.

These panels and doors have their adjacent edges in substantiallyabutting relation, their outer surfaces being in substantially the sameplane and presenting a plain flush outer face. The outer lateral edgesof the several doors and panels, preferably extend to the side edges ofthe frame 23 so that no parts of the latter are visible.

The particular features of the present invention reside in the oven andbroiler compartment rack and operating mechanism, more clearly shown inFigures 3, 4 and 7. Referring especially now to Figures 3 and 5, it willbe observed that there is provided a rack support comprising a verticalrectangular sheet metal frame 24 which has at its upper and lowercorners, at one side of said frame, a pair of bearing pins 25 and 26respectively which pins have their hearings in the upper and lower topand floor plates 21 and 28 respectively of the oven compartment 14%,permitting the rack to be swung in an arc of a circle within said oven.

It is to be particularly noted that the bearings for the rack arepositioned on an axis located forward 'of and at one side of the ovencompartment, as more clearly illustrated in Figure 6, or in other wordsat a point closely adjacent the corner of said oven in proximity to theoven door hinge, for purposes which will be presently observed.

Specifically, the sheet metal frame 24 has its side frame members 30provided with a vertical series of recesses 3| formed by punchingthrough the sheet metal frame members in opposite directions at spacedintervals to provide a vertical series of lips'32, which cooperate witha finger or hook 33 and brace 35 to maintain the said tray support inproper position upon the swinging rack. The broiler pan which isremovably mounted upon the support 34 is shown at 36, while anadditional cooking vessel rack is shown at 31 the latter also beingremovably supported upon the swinging rack by means similar to that forthe broiler pan support. a

As will be more clearly observed from an inspection of the view inFigure 6, in which the movable partsare shown in full and dotted lines,the arrangement of the mounting of the swinging frame is such that itmay be conveniently swung from a position entirely within the oven, to aposition such that the pans and supports carried thereby may be movedentirely out of the oven.

The rack is so constructed, that it may be operated either through anoperative connection with the oven door 4, or independently thereof, andto this end, we provide the selective mechanism to be now described.

Rigidly attached to the lower' corner. of the rack 24, on the axis ofthe lower bearing 26 is a spring metal arm 38, which lies substantiallyparallel with the long side of the pan support 34, said arm at its outerend having a lateral stud 50 carrying a pair of anti-friction rollers4|, which are adapted, when desired, to cooperate and ride inthe'channels 42 of a guide member 43 rigidly secured to the inner faceof the door 4 toward its lower edge.

By this construction, it will be manifest that when the door is closedand opened, the rollers M on the end of the spring arm 38 may ride inthe channeled guide member 63, resulting in the swinging of the rack 24to bring the supports carried thereby, into and out of the ovensimultaneously with the movements of said door.

, the,oven door 3 without at the same time swinging the rack 2t, and topermit of such operation,

we provide a selective mechanism shown particularly in Figure 4. Thismechanism comprises a lever 46 pivoted intermediate its ends on a pininclined shifter-plate 47, which as shown in Fig.

3 normally extends through an opening 50 in the inner plate of the doorand is disposed outside the space between said door plates due to theaction of a coiled spring &8, the upper portion of one leaf of whichengages the upper end of lever :84 and urges it into the positionindicated in Fig. 7. In such position, the shifter plate extends overthe entrance to the guideway member 43, and guides 'the,rollers M on thearm 38 over, instead of into said guideway.

Under normal operating conditions, the parts are in the position shownin Fig. 7, that is, with the shifter plate 47 projected so that the rearedge thereof extends over the entrance to the channeled guide member 43.As now positioned,

. when the door is opened, the said anti-friction the door may openwithout imparting any movement to said rack and the parts carriedthereby.

However, when it is desired to cause the simultaneous operation of therack and door, that is to have the rack swing out of the oven when thedoor is opened, the operator by pulling downwardly on the handle 52,causes the inner end to engage the upper end of the lever M, moving saidlever on its pivot 45 against the action of the spring 48 from the fullline position shown in Fig. 7 to the full line position shown in Fig. 4,at which time, the rollers 4! will be permitted to ride into theentrance 5! of the channeled guideway 43. Opening of the door 4outwardly into the position shown in Fig. 3 where ready access may behad to the articles disposed upon the racks or broiler. Referring toFig. 2, the broiler burner is shown at 60 and the oven burner at 6|.

While it is preferredto impart swinging movement to the rack through theconnections with the door as hereinbefore described, the rack may beswung independently of the door. Thus, as indicated in Fig. 1, whereinthe door 4 swings about a horizontal axis, the rack or ,frame 24 may beswung into and out of the oven compartment by hand.
